The newest version of Skype lets you initiate IMs and video chat sessions with Facebook users, even if they aren't running Skype. It also includes group screen sharing, a push to talk feature, and HD video for certain webcams.

We mentioned some of these features when they came out in beta, but they've now made it to the stable version of Skype, so everyone can get in on them. All you need to do is connect your Facebook account to Skype, and you'll be able to view your news feed, message your friends, and start video chats with them. Premium users can also use the new group screen sharing feature, and all users can set up a "Push to Talk" hotkey in the app's preferences, which is perfect for chatting while playing video games. Lastly, if you have a Logitech C920 webcam, you can enable full HD video calling, since that camera supports video encoding inside the camera itself. Hit the link to read more.
